PIPE.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed January 10, 1920. Serial No. 350,658.

To (AZZ 'fw/omi it may concern:

lie it known that l, lVILLiAM. Ewen'r, a subject of the King of Great Britain, residing` at Falls View, Niagara Falls, Ontario, Canada, have invented Certain new and useful Improvements in Pipes, of which the following is a specilication.

This invention relates to smoking appliances, and the primary object of the invention is to provide an improved smoking pipe, so constructed as to prevent the clogging of the bore of the pipe by the tobacco and the wetting of the tobacco by the moisture accumulating in the pipe bore, thereby insuring a clear, sweet, smoke.

A 'further object ot'the invention is the provision of a tobacco pipe having an auxiliary stem,provided with a plurality of spaced passageways formed on its outer surface which communica-te with a longit-udinally extending slot bisecting the bore ot the supplemental stem. The passageways being so arranged as to preclude the choking thereof by tobacco.

A further object of the invention is the provision ot an improved smoking pipe having detachably associated therewith a supplemental stem provided with an upwardly and inwardly extending longitudinal slot which communicates with the bore ot the pipe, the stem being provided with a plurality of curved passageways for communi eating with the slot, the arrangement ot' the slot in the stem forminof a well so as to re vent the moisture accumulating in the stem from coming in Contact with the tobacco.

A still further object of the invention is to provide an improved means for holding a supplemental stem in the bore of the pipe against turning movement, so that the slot formed therein will be held in correct position.

A still further object of the invention is to provide an improved smoking pipe of the above character which is eflicient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost. f

Otherobjects of the `invention will appear in the following detailed description, taken in connection with the drawings, forming a part of this specification, and in f'wlnch drawings:

Figure l is a longitudinal section through the improved pipe showing the supplemental stem in elevationl Fig. 2 is a similar view showing the supT plemental stem in section.

Fig.. 3 is a longitudinal section through the pipe with the bit removed and the sup plemental stem partly withdrawn from the pipe bowl, and

Fig. 4 is a detail transverse section taken on the line 41E- 4c of Fig. 2.

Referring to the drawings, in detail, wherein similar reference charac-ters desig nate corresponding parts throughout the several views, the letter A indicates the improved pipe which includes the bowl B, the stem C, the bit D and the supplemental stem E. v

The pipe bowl B and the stem C may be ot' the ordinary or any preferred construction and may be formed ot any desired material, such as hard wood, meerschaum, or the like, and the stem C is provided with a relatively large longitudinally extending bore 5 for the reception of the supplemental stem E. The bore 5 of the stem C communicates with the bowl B and the lower end of the bowl is provided with an inwardly extending circular notch 6 which is in direct alinement with the bore 5 and is adapted to receive the in ner end of the supplemental stem E when the same is placed in its operative position in the stem B. I

The supplemental stem E includes a cylindrical body 7, `formed of hard wood or the like and is ol suflicient size to snugly it in the bore 5 ot the stem and trictionally en gage the wall thereof. The outer end oit the cylindrical body '7 is provided with a screw threaded terminal 8 for the reception of the bit D which may be made of hard rubber, amber or the like, and the inner end of the bit D is provided with a threaded socket 9 for the reception of the threaded extension 8 ot the body 7.` The bit D is pro-v vided with a longitudinally extending bore 10 which is in direct alinement with the lon! gitudinally extending bore ll Jformed inthe cylindrical body Land the bores 10 and 1l form the passage-way for the smoke from the pipe bowl to the mouth of the user. The inner end of the cylindrical body 7 is provided with a relatively coarse external screw thread 12, `which provides a plurality of tortuous channels 18 and the lower face of the cylindrical body 7 at this point is provided with an inwardly extending lon 'tudinal slot 14:, with which the tortuous c annels or passages 13 communicate.

The longitudinal slot la'extends substantially half way through the cylindrical body 7 and terminates at the longitudinal axis of the same and communicates with the bore 1l. The cylindrical body 7 is adapted to be positioned in the stem C in such a manner that the slot lll will beat the lower end ot the bore 5 of the stem and directly below the bowl B, This slot prevents water, saliva, moisture or the like, from entering into the pipe bowl, and `lorms a well i'or thD collection oi the saine. liach of the passageiys or channels l as stated communicates` v ith the slot la, and thereby provide a plurality ot diilerentA openings tor the entrance of smoke into the bore ll and if any one of or a number of the passageways become clogged the smoke will still have an outlet or outlets through the bore. To prevent twisting or turning movement of the supplemental stem E in the-stem C, a radially extending lug l5 is formed on the outer end of the supplemental stem and the lug is adapted to be received in a notch 16 formed in the outer face of the stein C, yThis lug is placed diametrically opposite the slot le and forms means for permitting the smoker to exactly determine the position of the slot lll in relation to the bowl B when the supplemental stem is placed in position, and it will be seen that when the lug l5 is placed in the notch 16 the slot will be in its correct position. Y v

In operation of the improved smoking pipe A, the supplemental stem lil is slid into the enlarged bore 5 of the stem C until its inner end engages in the pocket 6 and the lug-l5 fits into the notch 16. rlhe bit D is then threaded on the forward extension 8 into engagement with the outer face' of the stem C. Upon the loading of the pipe and the lighting ot the same, the smoke will circulate around the channels oi' the passageways 13 into thevbores ll and l0 and into the mouth of the user.

From the .foregoing description be seen that anl improved Vsmoking provided in which thecholring of it can pipe is the bore is vabsolutely pievented'and which will maintain the tobacco'in a'dry condition.

Changes in vdetails may be made without departing from the spirit or scope of my invention; but, L l

l claim: l. The combination with a pipe including' a'bowl and a stem having a bore communicating with Vthev lower end of the bowl, of

a supplemental stem fitted in the first-named stem an'd having Va smoke passage formed therein, the inner end of the supplemental steniprojecting into the lower end oi the bowl and having an inwardly extending slot communicating with the smoke passage, and a plurality of spaced channels coininunicating with the slot.

2. rEhe combination with a pipe including a bowl and a stein having a relatively large bore communicating with the lower end oil the bowl, ofa supplemental stem tted in the bore and having a smoke passage, the inner end of the supplemental stein projecting into the bowl and having an inwardly extending slot communicating" with the smoke passage, andaV plurality of tortuous passages formed on the outer surface of the stem at the inner end thereoi" and communicating with the slot.
